Title: "S-Store: A Streaming NewSQL System for Big Velocity Applications"
Managing high-speed data streams in real time has become an integral part of todaya s big data applications. In a significant portion of these applications (e.g., leaderboard maintenance, online advertising), we see a critical need for real-time stream processing to co-exist with transactional state management. Yet, existing systems treat streaming and transaction processing as two separate computational paradigms, which makes it difficult to build such applications to execute correctly and scalably. S-Store is a new data management system that provides a single, scalable platform for transactional stream processing. S-Store takes its architectural foundation from H-Store - a modern distributed main-memory OLTP/NewSQL system, and adds well-defined primitives to support data-driven processing such as streams, windows, triggers, and workflows. Furthermore, it makes a number of careful extensions to H-Store'straditional transaction model in order to maintain ACID guarantees in the presence of data and processing dependencies among transaction executions that involve streams. In this talk, I will present S-Store's design and implementation, and show how S-Store can ensure transactional integrity without sacrificing performance.
Nesime Tatbul is a senior research scientist at the Intel Science and TechnologyCenter for Big Data based at MIT CSAIL. Before joining Intel Labs, she was afaculty member at the Computer Science Department of ETH Zurich. She receivedher B.S. and M.S. degrees in Computer Engineering from the Middle East TechnicalUniversity (METU), and her M.S. and Ph.D. degrees in Computer Science from BrownUniversity. During her graduate school years at Brown, she also worked as aresearch intern at the IBM Almaden Research Center, and as a consultant for theU.S. Army Research Institute of Environmental Medicine (USARIEM). Her researchinterests are in database systems, with a recent focus on data stream processingand distributed data management. She is the recipient of an IBM Faculty Award in2008, a Best System Demonstration Award at the ACM SIGMOD 2005 Conference, andboth the Best Poster Award and the Grand Challenge Award at the ACM DEBS 2011Conference. She has served on the program committee for various conferencesincluding ACM SIGMOD (as an industrial program co-chair in 2014 and as a groupleader in 2011), VLDB, and IEEE ICDE (as a PC track chair for Streams, SensorNetworks, and Complex Event Processing in 2013). She has chaired a number ofVLDB co-located workshops including the International Workshop on DataManagement for Sensor Networks (DMSN) and the International Workshop on BusinessIntelligence for the Real-Time Enterprise (BIRTE). Her recent editorial dutiesinclude PVLDB (associate editor, Volume 5, 2011-2012) and ACM SIGMOD Record(associate editor, Research Surveys Column, since June 2012).
